WebThis formula tells us the shortest distance between a point (𝑥₁, 𝑦₁) and a line 𝑎𝑥 + 𝑏𝑦 + 𝑐 = 0. Since the radius is perpendicular to the tangent, the shortest distance between the center and the tangent will be the radius of the circle. 𝑥 = 5 This can be rewritten as: 𝑥 - 5 = 0 Fitting this into the form: 𝑎𝑥 + 𝑏𝑦 + 𝑐 = 0 We see that: 𝑎 = 1 𝑏 = 0 WebFeb 12, 2024 · Answer: Firstly, you need to divide the diameter by two to estimate the radius of the circle using the formula r = d/2 = 5 cm or use another tool: the circle calc: find r.
